Scientific Highlights

The translational project "PROGNOSTICS", proposed by a consortium led by Prof. Roger Schibli, received CHF 2 million funding from the PHRT initiative of the ETH Domain(https://www.sfa-phrt.ch/two-clinical-trial-projects-launched-transforming-clinical-care-with-eth-technologies/). The study is being conducted with the Co-applicants Prof. Dr. med. Damian Wild at the University Hospital Basel and Prof. Dr. Nicola Aceto of the ETHZ. The consortium will test a new radiopharmaceutical developed at the Center for Radiopharmaceutical Sciences in 36 patients with advanced prostate cancer.

In this paper we present a model system built out of artificially layered materials, allowing us to understand the interrelation of magnetic phases with the metallic-insulating phase at long length scales, and enabling new strategies for the design and control of materials in devices. The artificial model system consists of superlattices made of SmNiO₃ and NdNiO₃ layers, – two members of the fascinating rare earth nickelate family, having different metal-to-insulator and magnetic transition temperatures. By combining two complementary techniques ....

We report resonant elastic x-ray scattering of long-range magnetic order in EuPtSi₃, combining different scattering geometries with full linear polarization analysis to unambiguously identify magnetic scattering contributions. At low temperatures, EuPtSi₃ stabilizes type A antiferromagnetism featuring various long- wavelength modulations. For magnetic fields applied in the hard magnetic basal plane, well-defined regimes of cycloidal, conical, and fanlike superstructures may be distinguished that encompass a pocket of commensurate type A order without superstructure.

Muon spin rotation with low-energy muons (LE-μSR) is a powerful nuclear method where electrical and magnetic properties of surface-near regions and thin films can be studied on a length scale of ≈200 nm. This study shows the potential of utilizing low-energy muons for a depth-resolved characterization of oxide-semiconductor interfaces, i.e., for silicon (Si) and silicon carbide (4H-SiC). The performance of semiconductor devices relies heavily on the quality of the oxide-semiconductor interface; thus, investigation of defects present in this region is crucial to improve the technology.
